The exchange of data between participants within inter-organizational networks becomes a prominent field of action. However, intra-organizational data governance mechanisms reach their limits across company boundaries. Current research barely addresses the need to model organizational data governance roles for managing inter-organizational networks. Therefore, this contribution aims to identify existing data governance roles in an inter-organizational context. A literature review is conducted to provide a holistic overview of data governance roles. Then, these results are concatenated with network management requirements, gathered from inter-organizational management research, to take a first step in shaping an inter-organizational role model for data governance. Limitations include the lack of evidence on the practical applicability of the results and the lack of heterogeneity in the research background.
